FIELD OF THE INVENTION

The present invention relates to a heteroaryl derivative, a stereoisomer thereof, a hydrate thereof, a solvate thereof, or a pharmaceutically acceptable salt thereof, a method for preparing the same, and a pharmaceutical composition for the prevention or treatment of cancer, comprising the same as an active ingredient.

BACKGROUND OF THE INVENTION

The occurrence of cancer is related to various environmental factors including chemical substances, radiations and viruses, and to changes of oncogenes, tumor suppressor genes, genes associated with apoptosis and DNA repair and the like. Recently, the molecular mechanism of these cancers could be figured out, and thus it could make a new treatment method, i.e. a targeted cancer therapy possible. In general, targeted therapeutic agents may be so prepared that they may show their effects by targeting the molecules that cancer cells possess as their own characteristics. The genes regarded as a molecular target are those associated with signal transduction pathway of cancer cell, angiogenesis, extracellular matrix, cell cycle regulator, apoptosis and the like. An important targeted therapeutic agent used in the current therapy includes tyrosine kinase inhibitors as well as ‘signal transduction pathway inhibitors’ and ‘angiogenesis inhibitors’. In this connection, it has been found that a protein tyrosine kinase plays an important role in a number of malignant tumors. In particular, it has been known that epidermal growth factor receptor (EGFR), which is a receptor tyrosine kinase of ErbB family, is abnormally activated in a number of epithelial cell tumors including non-small cell lung carcinoma (NSCLC), breast cancer, glioma, squamous cell carcinoma of head and neck, colorectal cancer, rectal adenocarcinoma, head and neck cancer, gastric cancer, and prostate cancer, wherein the activation of the above EGFR-tyrosine kinase causes a persistent cell proliferation, invasion of the surrounding tissue, remote metastasis, and angiogenesis, and increases a cell survival.

Specifically, the EGFR is one of the members of ErbB tyrosine kinase receptors family and also a transmembrane tyrosine kinase having an extracellular ligand-binding domain and an intracellular domain including a tyrosine kinase domain, wherein it can include EGFR (referred to as ErbB1 or HER1), HER-2 (referred to as ErbB2 or neu), ErbB-3, and ErbB-4 (referred to as HER4). If a ligand binds to a receptor forming homodimer or heterodimer, a tyrosine kinase in a cell is activated, so that a signal stimulated by EGFR in this way also activates a signal transduction pathway of phosphatidylinositol 3-kinase (PI3K/AKT/mTOR, RAS/RAF/MAPK and JAK/STAT) (non-patent literature 0001). In particular, EGFR is overexpressed in more than a half of non-small cell lung cancers (NSCLC), and thus a number of studies have been carried out, in which EGFR is a target of a therapy. So EGFR TKI (tyrosine kinase inhibitor), inhibiting an activity of EGFR tyrosine kinase, has been developed, wherein representative drugs thereof include Gefitinib (IRESSA™), erlotinib (TARCEVA™), lapatinib (TYKERB™, TYVERB™) and so on.

On the other hand, in year 2004, it was reported that an activating mutant of EGFR is correlated with a response to gefitinib therapy in non-small cell lung cancer (non-patent Literatures 0002 and 0003). Specifically, it has been known that the above EGFR mutation is largely classified into a sensitizing mutation and a resistant mutation, wherein an exon 19 deletion and an exon 21 L858R point mutations are most important sensitizing mutations and make up about 85 to 90 percent of the sensitizing mutation. Especially, it has been also known that the exon 19 deletion mutation is more sensitizing to the TIK. On the other hand, it has been known that the exon 20 T790M point mutation is a most important resistant mutation and is found in more than 50 percent of acquired resistant patients (non-patent literature 0004).

Somatic mutation identified hitherto includes an in-frame deletion in exon 19 or an insertion in exon 20, as well as a point mutation in which a single nucleic acid residue is modified within an expressed protein (e.g. L858R, G719S, G719C, G719A, L861Q) (non-patent literatures 0005 to 0007).

Despite an initial clinical effect of gefitinib/erlotinib in NSCLC patients with an EGFR mutation, a progressive cancer develops in most patients in the end while these patients are undergoing a therapy using these medicines. In an early study of recurred samples, a secondary EGFR mutation, T790M, was identified, which made the gefitinib and erlotinib to be an ineffective inhibitor of EGFR kinase activity (non-patent literatures 0008 and 0009). It has been proved in the follow-up studies that the EGFR T790M mutation was found in approximately 50 percent (24/48) of tumors derived from the patients who acquired a resistance to the gefitinib or erlotinib (non-patent literatures 0010 to 0012). This secondary genetic modification in the patients treated by a kinase inhibitor is caused in a position similar to a ‘gatekeeper’ residue and a secondary resistance allele associated therewith (e.g. T3151 within ABL in imatinib resistant CML).

Also, it has been known that EGFR_del19 or EGFR_L858R as EGFR mutation is a major cause of non-small cell lung cancer, and head and neck cancer. Thus, IRESSA and TARCEVA as therapeutic drugs of said cancers were developed and are currently used in clinical trials. However, when such drugs were administrated for cancer patients, an acquired resistance, in which an EGFR secondary mutation based on the structure of the drugs, was observed. In addition, it was also found that such a thing was a major cause of the actual resistance to drugs. For example, if a first generation inhibitor of EGFR is used for 10 months in average, the acquired resistance, referred to as T790M mutation positioned in a gatekeeper of EGFR kinase, occurs, resulting in preventing the first generation inhibitor of EGFR from showing a medicinal effect. That is, EGFR_del19_T790M or EGFR_L858R_T790M double mutation occurs, resulting in preventing existing therapeutic agents from exhibiting a medicinal effect.

<Experiment Example 1> Evaluation of Ba/F3 Proliferation Suppression Activity

A following experiment was carried out to evaluate the suppression activity of the compounds according to the present invention against the proliferation of Ba/F3 which expresses EGFR mutations.

For the Ba/F3 cells, a RPMI-1640 medium containing 10% FBS and 5 ng/ml IL-3 (R&D Systems) was used. The transduced Ba/F3 cells were cultured in a medium, which is same as the above medium, but 1 ug/ml puromycin (Invitrogen) was additionally added to.

24 hours before the treatment of the cells with the compounds, 3000 to 5000 cells were distributed into each well of a white clear bottom 96 well plate (Corning). The compounds were diluted in a dimethyl sulfoxide (e.g. dilution ratio of 3:1 and total 12 concentrations) and then injected by 0.5 ul respectively, such that a final concentration amounted to 0.3 nM to 50 uM. 72 hours after the treatment with the compounds, the measurement of live cells was made in such way that these cells were stored for 10 minutes at a room temperature using a CellTiter-Glo luminescent cell-viability reagent (Promega) and then their luminescence intensities were measured using a reader (i.e. Synergy Neo, Biotek). Each test was repeated three times.

resulting values were calculated as a cell growth ratio (%) compared to a control. Then, the graphs were drawn and the G150 values were calculated by using a program, GraphPad Prism version 5.0.

A following table 2 shows the evaluation results of the suppression activity against the proliferation of Ba/F3 cells expressing EGFR mutations:
